How to replicate SELinux policies among Linux machines

SELinux or Security Enhaced Linux, is a set of kernel modification & user-space tools, that implements access policies called MAC (Mandatory access controls). It reduces privileges for any server or service to minimum required to work, thus eliminating problems due to unchecked privileges.

With SELinux, there is no concept for root user or super user & also does not have short comings of Linux security mechanism, for ex dependence on setuid/setgid. We have already discussed SELinux in detail in our article Beginner’s guide to SELinux. Please refer the article to learn about SELinux in detail.

In this tutorial, we are going to discuss how we can replicate SELinux policies of one system to another system. But before we do that let’s discuss pre-requisite,
